ROY L. NAUGLE, orviinac zsroim; vmcmm.

To all whom it may concern.

Be it 'known that I, ROY. L. ,NAUGLE, a citizen of the United States, residing at Blackstone, in the county of Nottoway and State of Virginia, have invented certain'new and useful Improvements in Steam-Generators, of which .the following is a specification, reference being had to the accompanying drawings. s

This invention relates to certain improvements in steam generators and it is an object of the invention to provide anovel and improved device of this general character wherein a liquid fuel is employed and wherein the water to be converted is delivered into a chamber wherein the combustion of the fuel occurs.

It is also an object of.'the invention to.

provide a novel and'improved steam generator wherein fuel, air and water are delivered within a chamber at substantially equal pressure andso fed to and mixed within the chamber to bring about combustion within the chamber and converting the water into steam so that all of the heat given off by the fuel is. utilized. I

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved steam valve whereby certain imporare attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will bev hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein is disclosed a diagrammatic view illustrating a steam generator constructed in accordance with an embodiment of my invention. I

As disclosed in the accompanying drawings 1 denotes a tank of predetermined dimensions and which is adapted to contain a supplv of water and a supply of air under pressure. I denotes an elongated pipe of predetermined dimensions and which leads to'an engine, or the like. In communication with the pipe P through the closed end 2 thereof is atconduit 3 leading from a source of fuel supplyvand which source is herein disclosed as a tankfl. The fuel within the tank 4 is preferably crude petroleum. In

communication with the conduit 3 in close proximity to the point of communication of said conduit with the pipe P is a second conduit 5 leading from the upper portion of the tank 1 and through which the air in said tank 1 is adapted to pass. In communication the lower portion or bottom of the tank 1 is a conduit 6 leading to and communicat-- ing with the pipe P at a predetermined point inwardly of the closed end 2 thereof. Interposed in the conduits 5 and 6 are the manually operated controlling valves 7 and 7 respectively. The conduit 3 has also interposed therein a controlling valve 8. Also in communication with the tank 1 through the bottom thereof and with the tank 4 through the bottom of said last named tank is the conduit 9'wliereby the pressure within the tanksl and 1 is equalized so that the fuel within the tank 4 is automatically forced upwardly and through the conduit 3. Also interposed in the conduits 3, 5 and 6 are the regulating valves 10 arranged in close proximity one to the other and provided with stems 11 extending exteriorly of said conduits. Each of the valves 10 has coacting therewith a spring 14 which constantly urges said valve into closed position.

Pivotal] y engaged as at a with the stem 11 of the valve coacting with the air conduit 5 are the rods 12 which have their opposite end portions engaged with the sliding fulcrums 21 mounted upon the supports or guides 22. Pivotally engaged as at b with the outer end portion of each of the rods 12 and inwardly of theadjacent fulcrum 21 is a stem 11 of each of the two remaining valves. By this arrangement it will be perceived that as the valve '10 coacting with the conduit 5 moves into open position, the remaining two valves will also be caused to move into an open position through the mediums of the rods 12'. By adjusting the fulcrums 21, the lift of the valves coacting with the conduits 3 and 6 may be increased or decreased in accordance with the requirements of practice.

At a. point intermediate the closed end 2 and the point of communication therewith of the conduit 6, the pipe P has depending therefrom a draft vent 15 having interposed therein the controlling valve 16 and positioned directly beneath the vent 15 is a gasolene torch 17 of any desired type. Also in communication with the portion of the pipe P intermediate the closed end 2 thereof and the point of communication therewith of the conduit 6, is a priming cock 18 for a purpose which will "hereinafter be more part cularly referred to. At a predetermined location inwardly of the point of communication of the conduit with the pipe P, said pipe P is provided with an up-standing vent 19 adapted for communication with the atmosphere and which has interposed therein the controlling valve 20.

In operation the delivery end of the pipe P is closed by a suitable valve (not shown) as is also the valves 7 and 8. The valves 16 and 20 are open. Before the valve 16 is opened, gasolene or other volatile l1quid fuel is delivered within the pipe P through the priming cook 18. After the valve 16 is opened, the torch 17 is lighted and the flame will pass through the draft vent 15 and 1gnite the fuel within the pipe and this flame will discharge through the open vent 19. When sufficient heat has been generated within the pipe P, the valve 7 is partially opened and the valve 8 completely opened. This will result in a mixture of air and fuel delivered in the pipe P through the closed end thereof and which will be ignited within the pipe P At this time the valve 16 is closed and the valve 7 opened to permit delivery of water into the pipe P and the water as delivered within the pipe P will be converted into steam. When sufficient steam pressure has been generated within the pipe P, the valve interposed therein at the delivery end is openas is also the valve 20, while the valves 7 and 7 are both opened wide. At this time the valves 10 automatically operate to control the flow of fuel, air and water to the pipe P. It is to be noted that all three of the valves 10 are operated under control of the air pressure so that when the steam pressure within the pipe P is reduced, the pressure of the air will serve to cause the valves 10 r to open and vice versa.

From the foregoing description, it is thought to be obvious that a steam generator constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated and it will also be obvious that my invention is susceptibleof some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.
